A Rh(III)-catalyzed one-pot reaction of benzamides, ketones, and hydrazines for facile access to isoindolinones is reported. In this method, various ketones are transformed into donor–donor diazo compounds, which sequentially engage in insertion with benzamides under Rh(III) catalysis to generate N-substituted quaternary isoindolinones.

The asymmetric C–H annulation of O-pivaloyl 1-indolehydroxamic acid with donor/acceptor diazocompounds has been achieved for the first time, to the best of our knowledge, by using a rhodium catalyst embedded in a chiral binaphthyl backbone. This protocol constitutes a straightforward route for the synthesis of a new family of 1,2-dihydro-3H-imidazo[1,5-a]indol-3-one derivatives having a quaternary
据我们所知,通过使用嵌入在手性联萘骨架中的铑催化剂,首次实现了O-新戊酰基1-吲哚羟肟酸与供体/受体重氮化合物的不对称CH环化。该协议为合成具有季碳立构中心的1,2-二氢-3 H-咪唑并[1,5- a ]吲哚-3-one衍生物的新家族提供了一条简单的路线,该路线具有高收率和出色的对映选择性(至98:2 er)。
Cp*Rh(<scp>iii</scp>)-catalyzed regioselective cyclization of aromatic amides with allenes
A new Cp*Rh(III)-catalyzed regioselective cyclization reaction of aromatic amides with allenes is reported. The use of allenyl derivatives bearing a directing-group assistant as a reaction promoter was the key to the success of this protocol. In this catalytic system, N-(pivaloyloxy)benzamide substrates react with allenes via Rh–σ–alkenyl intermediates, while N-(pivaloyloxy) indol substrates react
报道了一种新的 Cp*Rh( III ) 催化的芳香酰胺与丙二烯的区域选择性环化反应。使用带有导向基助剂的丙二烯基衍生物作为反应促进剂是该方案成功的关键。在该催化体系中, N- (新戊酰氧基)苯甲酰胺底物通过Rh-σ-烯基中间体与丙二烯反应,而N- (新戊酰氧基)吲哚底物通过Rh-π-烯丙基中间体反应。这些反应具有反应条件温和、底物范围广、官能团相容性高等特点,得到了多种高价值的异喹啉酮和嘧啶并[1,6- a ]吲哚-1( 2H )-1骨架化合物。还研究了合成应用和主要机制。
